Knowledge of the position and configuration of the mandibular canal is a basic requirement before implant placement in the mandible. Radiological studies suggest a positive correlation between alveolar trabecular bone quality and mandibular canal corticalization. The aim of this study was to test this assumption histomorphometrically in the anterior molar(More)
Sclerostin is a Wnt signalling antagonist that controls bone metabolism. Sclerostin is expressed by osteocytes and cementocytes; however, its role in the formation of dental structures remains unclear. Here, we analysed the mandibles of sclerostin knockout mice to determine the influence of sclerostin on dental structures and dimensions using(More)
OBJECTIVES Adaptations of the alveolar ridge after tooth loss have been well described. However, studies on the morphometric characteristics of cortical bone are rare; hence, this study of human atrophic edentulous mandibles was undertaken. MATERIAL AND METHODS Total cortical area, porosity, and thickness, and the percentage of cortical area in the(More)
OBJECTIVE The first objective of this pilot study was to evaluate the impact of the hydrophilicity on the early phases of osseointegration. The second objective was to compare two hydrophilic implant surfaces with different geometries, surface roughness, and technologies achieving hydrophilicity. MATERIAL AND METHODS Twelve weeks after extraction, all(More)
Fosfomycin monotherapy was compared to therapy with vancomycin for the treatment of implant-associated methicillin-resistant Staphylococcus aureus (MRSA) osteomyelitis in an experimental rat model. The proximal tibiae were inoculated with 15 μl of a suspension containing 1×10(8) to 5×10(8) CFU/ml of a clinical isolate of MRSA with simultaneous insertion of(More)
AIM Pharmacological inhibitors of prolyl hydroxylases, also termed hypoxia-mimetic agents (HMAs), when repeatedly injected can support angiogenesis and bone regeneration. However, the possible role of HMA loaded onto bone substitutes to support angiogenesis and bone regeneration under diabetic condition is unknown. The capacity of HMA loaded onto(More)
BACKGROUND Evaluation of the marginal fit of cemented zirconia copings manufactured after digital impression with Lava™ Chairside Oral Scanner in comparison to that of zirconia copings manufactured after conventional impressions with polyvinyl siloxane. METHODS A prepared typodont tooth #36, was replicated 40 times with a vinyl silicone and precise model(More)
AIM Vitamin D deficiency is considered to diminish bone regeneration. Yet, raising the serum levels takes months. A topic application of the active vitamin D metabolite, calcitriol, may be an effective approach. Thus, it becomes important to know the effect of vitamin D deficiency and local application on alveolar bone regeneration. MATERIAL AND METHODS(More)
AIM TNF-α is a pathological factor causing the characteristic symptoms of periodontal disease and rheumatoid arthritis. In this study we describe the phenotypes of human tumor necrosis factor (TNF)-α transgenic mice (hTNFtg) with respect to their periodontium and the temporomandibular joint (TMJ). MATERIAL AND METHODS Periodontal structures, TMJ, and(More)
